Refreshed after a nights’ sleep I jumped back on the New G Sunday morning. Adjusting the trip switch reset was an easy matter. Then it has to be checked that this adjustment didn’t throw another one off. I usually chase these trip adjustments back and forth til I get it right. The A side was still not picking up.I ohmmed the wire from the reverse switch to the leaf blade and had continuity. ???? Was this replacement contact I got my buddy in California bad? I had pulled that blade once and polished the contact area. It wasn’t sagging loose. I pulled the pinbank, lifted the contact block and removed the white plastic contact. By gosh, I was going to ohm it from the tip to the bottom. That is when I noticed a very small piece of plastic covering the bottom metal contact that rides on the leaf blade. When I pulled the contact out of the little plastic bag it was in somehow this piece of plastic got stuck in just the right place. Feeling like a chump I put everything back together minus the plastic and watched the mechanism merrily pick up A sides.

Now I can check the “corners”; A1/A2 and K9/K10. If the mech will pick up these four selections then the contact block alignment is perfect. Right side K10 was having trouble. K9 was picking up every time but after rejecting it and reversing the mechanism just didn’t seem to be travelling far enough left to lock onto this spot. I moved the right side reverse switch bracket an 1/8″ to the right to allow the mech to get a little more momentum coming off the turn and that did the trick.

Just for the heck of it I pulled the amp tubes and retested. The 6SN7 was weak. I didn’t think this was causing the hum which seems to have gone away but it got replaced nonetheless. So I seem to have a working machine. Onto other things.

I installed the finished pinbank, re-aligned the rack to the mech, and then aligned the pinbank and contact block to the rack. With the free play unit set I started making selections. Now is the “fun time” when little problems crop up and I do my best to fix them without tearing my hair out. Some jukeboxes have very few problems, some can be a booger bear to get sorted out. This one is making selections properly and picking them up. Everything seems to be OK but there is no A side pickup, the mech constantly trips after making a selection and when I do get the mech in Play there is a wicked loud hum. Turns out the trip wire wasn’t getting fully reset and stayed tripped. I can jiggle that with my finger while trying to figure out the rest. I replugged the tubes on the amp, pulled the mute plug, checked the ground on the RCA input to the amp, pulled the 4 inch speaker lead, checked the speaker wiring. No joy on the hum.

I cleaned the LC and RC contacts on the reversing switch and checked that they made properly. This is the switching for A/B pickup. This is where it actually splits into two legs going back to the contact block. It is the same circuit for both sides from the reverse switch back to the reciever through the 11 pin mechanism plug. The fact that the B side will pick up tells me the problem is from the reversing switch to the contact block. I checked the contact block and did not see a wire off. I’ll get it sorted tomorrow.

I’m really pleased with how the modification to the C upper back door worked out. The strip of wood allows the door to fit snugly in place. With it in place I checked that the lower door closed and fit well. The lower lock needed to be remounted. It is keyed the same as the cashbox lock which I like a lot. I can hand my customer two keys for all locks. Seeburg back doors are keyed the same as the side locks but they’re not always there. The coolest solution to a bunch of keys is when I have an extra back door lock to use for the cashbox door and can use one key for all locks. After checking the fit I took the upper back door off and laid it aside for access.
